On all Mac 10.8 bots, http/tests/misc/submit-post-keygen.html takes a very long time every time (15-30 seconds). When it hits 30 seconds, it times out.
I don't know what could be causing this. Locally, the test takes about a second.
Marked the test in <https://trac.webkit.org/r155732>.
Further updated expectations in <http://trac.webkit.org/r155877>.
Every time the test runs, it adds a key pair to keychain. No wonder that it hurts after many runs!
We should probably set up a temporary keychain for each DRT/WKTR instance.
The test case is updated in Bug 184428 to no longer bother the Keychain.
